Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
HIGH-FIBER-CONTENT FIBER-REINFORCED RIGID POLYURETHANE FOAM COMPOSITE PANEL AND METHOD FOR MANUFACTURING SAME
Provided are a high-fiber-content fiber-reinforced rigid polyurethane foam composite panel and method for manufacturing same; polyurethane resin is employed as a matrix material; comprised are a hybrid polyether polyol, a fire retardant, a hard-foam stabilizing agent, a coupling agent, a catalyst, a blowing agent, an antioxidant, an anti-UV agent, and isocyanate; fiber is employed as a reinforcing material and its content is greater than 60%. Using such technical means as a low-hydroxyl and low-functionality hybrid polyether polyol and a coupling agent solves the problem of insufficient impregnation of polyurethane resin with reinforcing fiber, thereby increasing the reinforcing-fiber content; it is thus possible to manufacture a fiber-reinforced rigid polyurethane foam material product having a density higher than 840 kg/m3 and a reinforcing-fiber content of more than 60%, compensating for the technical deficiency of fiber-reinforced polyurethane hard-foam composite panels, making their product specifications and performance more diverse, and satisfying different technical requirements.
